PUTPWENT(3C)PUTPWENT(3C)NAMEputpwent - write password file entry
SYNOPSIS
#include <pwd.h>
int putpwent(const struct passwd *p, FILE *f);
DESCRIPTION
The putpwent() function is the inverse of getpwent(). See getpwnam(3C).
Given a pointer to a passwd structure created by getpwent(), getp‐
wuid(), or getpwnam(), putpwent() writes a line on the stream f that
matches the format of /etc/passwd.
RETURN VALUES
The putpwent() function returns a non-zero value if an error was
detected during its operation. Otherwise, it returns 0.
USAGE
The putpwent() function is of limited utility, since most password
files are maintained as Network Information Service (NIS) files that
cannot be updated with this function. For this reason, the use of this
function is discouraged. If used at all, it should be used with put‐
spent(3C) to update the shadow file.
